How to reduce the convoluted bloat:
Nuke the star ratings, just have one and only one type of Fire Crystal.

Why should an effective strategy to farm radiants be rushing FSC's first depth?

Yes, I would enjoy farming radiants much easier... but I don't think being able to effectively farm radiants through spamming the first depth of certain missions.

Finally, my 1000 warm crystals will have a use other than to clutter my inventory.

I doubt it, since that wouldn't be "fair."

Also, I hate to be a grammar nazi... but it's "OOO IS planning" not "OOO are planning."

OOO is a singular group/collection of people/team. If we were talking about more than one group named OOO, then that's when it becomes plural. While the words "three rings" is something plural, when it is used as a proper noun, "Three Rings," to mean a group, it is then a singular noun. While Three Rings is made up of more than one person, the noun "Three Rings" is something singular.

@Arcknight: Yeah, you also edited your post to say that and I didn't see that until I had posted already. Before, I couldn't tell if you knew you were wrong or not. I usually don't pick at something small like this, but I see this common mistake quite often and it has become a bother to me.

Back on track....
OOO seems to be treating Missions as if they are the arcade themselves. While technically since the depths of Missions are found within the Clockworks, they aren't wrong in separating the two in regards things like drops. They also likely have a system in which it would make it hard to make Missions not drop Fire Crystals. So in order to achieve that, OOO would have to revamp Missions. Now while they may do something similar to revamping the Missions (I'm talking about changes we can't see ourselves but rather changes with how things work internally) for the Arcade Redux, I don't see the Arcade Redux being solely to make it where Fire Crystals are dropped only there. I do see the Arcade Redux as something that does separate the Missions from the Arcade, but I do also think the overall Arcade Redux will be something quite larger. Although changing it to make Fire Crystals only drop in the Arcade may be a step in the Redux. Basically, changing the drops to be exclusive in the Arcade isn't THE plan, but could be a step in the plan.

EDIT: You keep editing your posts while I'm typing a response. Also, if you are going to quote something, you might want to put a reference if you don't want me to think you pulled it out of thin air.

@Arcknight: All I'm saying is that if you are going to quote something as if it is taken from some sort of source, then you need to state the source otherwise there is no proof that you didn't just make it up and tried to make it look official. Also, I don't know the legitimacy of this "random discussion forum" you found it on. Neither do you, most likely. As for your "normally always right" adds no support to anything. Now if i knew you and trusted you because I had first hand experience seeing that you were normally always right, then it might add some weight. Telling me not to doubt you is illogical because I don't have first hand experience with your words. Well except with your saying "OOO are" which is incorrect.
